MEANS FOR CONNECTING AN IMPLEMENT TO A MOTOR Filed Dec. 26, 1928 1 J9 AT7 f zro /?z'cQ/-ds W w W ATTORNEY Patented July 26, 1932 ALONZORICHARDS, OF POMPTON LAKES, NEW JERSEY MEANS FOR CONNECTING AN IMPLEMENTTO .A MOTOR Application filed December 26,,1928. Serial No. 328,543.

This invention relates to means for interchangeably connecting a meatchopper and a sharpening tool to an electric motor so that either devicecan be driven from the motor, as

desired.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawing andspecifically pointed out in the appended claim.

In describing the invention in detail, reference will be had to theaccompanying drawing wherein like characters denote like orcorresponding parts throughout the several views, and in which 2- Figure1 is a sectional view showing a meat chopper driven by the motor.

Figure 2 is an elevation showing a grinding tool attached to the motor.

Figure 3 is a sectional detail view of the connecting means, with theparts separated.

Figure 4 is a section on line 4-4 of Figure 1.

Figure 5 is a section on line 5-5 of Figure 1.

In these views, the numeral 1 indicates the casing of the electric motorwhich is attached to the base 2, and 3 indicates the motor. A

hearing part 6 is attached to one end of the casing and the motor shaft7 extends into this part. This shaft is formed with a bore 8 at itsouter end which receives a plunger member 9 having a head 10 thereonformed with a projection 11. I prefer to make the bore and the stem ofthe plunger member of square shape in cross section, as shown in Figure5, so that the plunger member will retate with the shaft and the plungermember 0 is slidably arranged in the bore through means of the pin 12 inthe shaft engaging a groove 13 in the plunger member. The outer end ofthe shaft is flush with the inner wall of a socket 14 formed in theouter end of the 4 part 6, this socket being of square shape in crosssection. The inner end of the body of the chopper A, as well as theinner end of the body of the grinding tool B, is shaped to engage thesocket 14, as shown at 15, and

the extremity of this reduced part 15 is formed with a socket 16 toreceive the head of the plunger 11 and the head 17 of the shaft '18 ofthe chopper or tool. The head 17 is formed with a groove 19 to receivethe projection 11 of the head 10 of the plunger so as tolock the plungerto the head of the shaft and thus cause the shaft to be rotated by themotor when the parts are in operative position. A number of grooves 20,having recesses 21 at their inner ends, are arranged in each-reducedpart 15-, and plungers 22 are arranged in openings in the bearing part 6for engaging the recesses 21 to hold the chopper or grinding tool insaid part 6, it being understood that the plungers will pass through thegrooves 20 when the reduced part- 15 is pushed into the socket 14 andthen the plungers will enter the recesses and lock the parts together.The plungers are held in place by the ring 23 which surrounds a portionof the hearing part 6, this part 6 being provided with an annularenlargement in which the holes or openings for the plungers 22 areformed. A cam ring 24, having a cam-shaped interior circumference isrotatably arranged on the enlargement and is held in place thereon by acollar 25 which is suitably fastened to the ring 24. Thus in oneposition of the cam ring, the plungers 22 will be pressed inwardly so asto engage the recesses 21, and in another position of the cam ring, thesprings of the plungers 22 can force them outwardly so that they willrelease the part 15 and permit the same to be withdrawn from the socket14.

From the foregoing it will be seen that I have provided means wherebyeither a meat chopper, such as shown at A, or a grinding tool such asshown at B, can be attached to the motor in such a manner that the shaftthereof will be rotated by the motor.

It is thought from the foregoing description that the advantages andnovel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction andin the combination and arrangement of the several parts, provided thatsuch changes fall with- 00 in the scope of the appended claim.

What I claim is A two-part bearing for a pair of clutch connected shaftsections, one part of said bearing having a non-circular socket in whichone part of the clutch is received, the other part of said bearinghaving a reduced portion positioned-in said socketand of similarcross-sectional contour, a socket projecting from the reduced portion ofthe secondmen- 10 tioned part of the bearing and forming a con tinuitythereof, and adapted toreeeive-the other cooperating Clutch member,therespective sockets of said parts of the bearingheing arranged ininterfitting end .to end con '15 tacting engagement, said secondmentioned part ofthe bearinghavingoppoSed depressions, springpressed'plungersmounted onithe first mentioned part of the bearing andadapted to be received by the 'dQPIQEiOHS 20 for holding the respectivepartsiofithe hearing toget er, a ring:rotatablymountedon the firstmentioned .part ofthe bearing and having spaced cam surfaces :for"operating said plungers.
